Abstract

Disclosed is a multi-phase personal care composition comprising an aqueous phase, and an oil phase comprising volatile silicone, fatty acid amide and retinoid, wherein the aqueous phase is visually distinct from and in physical contact with the oil phase.

Claims (35)

1 . A multi-phase personal care composition comprising:

(a) an aqueous phase, and

(b) an oil phase comprising volatile silicone and retinoid,

wherein the composition comprises fatty acid amide and the aqueous phase is visually distinct from and in physical contact with the oil phase; and

wherein the volatile silicone to the retinoid is present in a weight ratio of from 10:1 to 1000:1.

2 . The multi-phase personal care composition according to claim 1 ,

wherein the retinoid is selected from retinyl ester, retinol, retinal and retinoic acid.

3 . The multi-phase personal care composition according to claim 1 ,

wherein the retinoid is present in amount of 0.00001 to 10% by weight of the total amount of the composition.

4 . The multi-phase personal care composition according to claim 1 ,

wherein the volatile silicone contains 3 to 10 silicon atoms.

5 . The multi-phase personal care composition according to claim 1 ,

wherein the amount of the volatile silicone is in the range of 3 to 60% by weight of the total amount of the composition.

6 . The multi-phase personal care composition according to claim 1 ,

wherein the fatty acid amide is in amount of 0.01% to 4% by weight of the composition.

7 . The multi-phase personal care composition according to claim 1 ,

wherein the composition comprises nonionic surfactant.

8 . The multi-phase personal care composition according to claim 1 ,

wherein both the aqueous phase and oil phase are transparent.

9 . The multi-phase personal care composition according to claim 1 ,

wherein the aqueous phase to the oil phase is present in a weight ratio of 1:8 to 8:1.

10 . Kit of parts comprising a cosmetic container, the multi-phase personal care composition according to claim 1 , and instructions for use of the kit.

11 . A method for preparing a personal care product comprising a step of shaking a cosmetic container containing the multi-phase personal care composition according to claim 1 , by human hand.

12 . A method for providing skin lightening to skin of an individual comprising the steps of (i) shaking a cosmetic container containing the multi-phase personal care composition according to claim 1 , by human hand and (ii) topically applying the resulting product.

13 . The multi-phase personal care composition according to claim 1 , wherein the retinoid comprises retinyl ester, retinol, or a mixture thereof, and wherein the retinoid is present in amount of 0.001 to 5% by weight of the total amount of the composition.

14 . The multi-phase personal care composition according to claim 1 , wherein the retinoid comprises retinyl palmitate, retinyl propionate, or a mixture thereof, and wherein the retinoid is present in amount of 0.1 to 0.6% by weight of the total amount of the composition.

15 . The multi-phase personal care composition according to claim 4 , wherein the volatile silicone is decamethylcyclopentasiloxane.

16 . The multi-phase personal care composition according to claim 5 , wherein the amount of the volatile silicone is in the range of 28 to 42% by weight of the total amount of the composition.

17 . The multi-phase personal care composition according to claim 7 , wherein the the composition comprises alkyl glucoside.

18 . The multi-phase personal care composition according to claim 9 , wherein the aqueous phase to the oil phase is present in a weight ratio of 1:2 to 2:1.

19 . A multi-phase personal care composition comprising:

(a) an aqueous phase, and

(b) an oil phase comprising volatile silicone and retinoid,
